Broker tech migration guide: from assessment to go-live in 7–14 days

Summary

Migrating a live forex broker from one technology stack to another is usually pitched as a multi-month project. It does not have to be. With disciplined scoping, reusable ETL jobs, and a rehearsed cutover plan, a Tier-2 broker running CRM, IB management, MT5, mobile app, KYC and three PSPs can be fully migrated in 7 to 14 calendar days with zero trading downtime. This guide documents the exact phases BrokerTech runs, the artifacts produced at each stage, the blockers we see most often, and a copyable timeline template broker ops teams can share internally.

Who this guide is for

This document is written for broker operations leads, CTOs and COOs who are evaluating a stack migration. It is most useful if one or more of the following applies:

• You are on a legacy CRM with annual license fees above $90,000 and renewal uplift clauses you cannot escape.
• Your current vendor bundles IB management as a paid add-on and your IB program is growing.
• You have three or more PSPs and every new PSP integration quote is measured in months, not days.
• Your MT5 manager plugins are patched by a third party who is slow to respond during incidents.
• You have a 12-month auto-renewal approaching and need an exit path that does not interrupt trading.
• You are launching a new regulated entity and want to avoid inheriting a monolithic legacy stack.

If none of those describe you, you probably do not need to migrate. If two or more describe you, the rest of this guide is directly actionable.

Phase breakdown

BrokerTech migrations run in four sequential phases. Each phase has a fixed duration window and a defined set of deliverables that must be signed off before the next phase begins. Signed off means a named person on the client side has reviewed and approved the artifact.

Phase 1 — Assessment (1–2 days)

The goal of assessment is to replace assumptions with a documented current state. Our team works directly with the client's ops and tech leads over two working days.

Deliverables produced in Phase 1:

• Current-state audit document. A written inventory of every system in the live stack: CRM vendor and version, MT5 server build and manager plugin list, PSP providers and their API versions, KYC vendor, email and SMS providers, reporting tools, and any custom scripts the ops team relies on.
• Data-mapping draft. A first-pass mapping between source-system tables and BrokerTech entities. This is a draft, not final — it will be revised in Phase 2 after we connect to the source database.
• Integration list. Every outbound and inbound integration point: PSP webhooks, MT5 gateway, KYC callbacks, email template APIs, affiliate tracking, BI exports. Each integration is classified as must-migrate, will-rebuild, or deprecate.
• Risk register. A ranked list of the top 10 risks for this specific migration with an owner and a mitigation plan for each. Regulatory sign-off windows and PSP re-certification timelines are always in this list.
• Effort estimate and timeline. A day-by-day plan for Phases 2–4 with named owners on both sides.

Phase 1 is offered free and carries no obligation to continue.

Phase 2 — Data migration (3–5 days)

Phase 2 is where the source database is actually read. We use a staged ETL approach: extract to a secure staging environment, transform against the finalized data map, load into a BrokerTech staging tenant that mirrors production.

Deliverables produced in Phase 2:

• ETL jobs. Versioned, re-runnable extract-transform-load scripts for each entity class (clients, accounts, positions, IB tree, transactions, KYC documents). Every job is idempotent — running it twice produces the same result.
• Validation reports. For each entity, a report showing source row count, target row count, rejected rows with reason, and field-level null-rate comparisons. A clean validation report is required before Phase 3 begins.
• Reconciliation diff. A financial reconciliation comparing source-system balances, open positions, and lifetime P&L to the BrokerTech staging tenant. Any variance above $0.01 per account is investigated and documented.
• Rollback snapshot. A frozen copy of the source database taken at the moment of final extraction, stored for 90 days post-cutover.

Phase 3 — Integration and testing (3–5 days)

Phase 3 wires the staging tenant to the live integration endpoints it will use in production, then runs structured tests.

Deliverables produced in Phase 3:

• PSP test transactions. For each PSP, a set of live test transactions covering deposit success, deposit failure, withdrawal approval, withdrawal reject, refund, and webhook replay. Screenshots and PSP reference IDs are captured in a test log.
• MT5 server cutover plan. A written plan covering manager plugin replacement, gateway re-pointing, group configuration migration, and the exact sequence of MT5 admin commands to be executed during go-live. The plan is rehearsed against a staging MT5 server at least once before go-live.
• UAT sign-off. A scripted user acceptance test executed by the client's ops team covering 30+ scenarios: client onboarding, KYC approval, deposit, withdrawal, IB commission calculation, IB payout, trader login to mobile app, password reset, 2FA enrollment, admin audit log review. UAT is signed off in writing.
• Performance baseline. Load test results for the critical paths: login, deposit, trade-view. Used as the post-cutover performance target.

Phase 4 — Go live (1–2 days)

Phase 4 is the switch. It is deliberately short because all the risk has been retired in Phases 1–3.

Deliverables produced in Phase 4:

• Parallel run checklist. For the first 24 hours, source and target systems both receive traffic for a defined subset of operations (typically read-only reporting). A checklist confirms parity on each check every hour.
• Rollback plan. A written, timed plan for reverting to the source stack if specific red-line metrics are breached. The rollback plan is signed off before cutover begins.
• Staff training. A 2-hour live session for the ops team on the new CRM, plus recorded walkthroughs for back-office, compliance, and support roles. Training materials are kept in the client's tenant.
• Cutover runbook. A minute-by-minute log of the cutover itself: who did what, when, and what the system response was. Archived for audit.
• 60-day hypercare plan. Named BrokerTech engineers on call for 60 days post-cutover with a defined response SLA.

Data-mapping checklist

The following checklist is the minimum entity coverage for a forex broker migration. Copy it into your internal planning document and mark each item with source-system location, target-system location, owner, and validation rule.

• Client records (personal details, contact info, residency, tax ID, status flags)
• Account balances (cash balance, equity, credit, bonus, negative balance protection state)
• Open positions (symbol, volume, entry, SL, TP, swap accrual, commission accrual)
• IB hierarchy (parent-child relationships across all tiers, effective dates, override rates)
• Commission history (per-trade commissions, per-lot rebates, tier bonuses, paid vs accrued)
• Deposit history (amount, currency, method, PSP reference, status, fees, FX rate if converted)
• Withdrawal history (same fields as deposits plus approval chain)
• KYC documents (document type, status, expiry, reviewer, timestamps, raw file)
• Activity logs (client-facing and admin-facing audit trails, login history, IP addresses)
• Email templates (transactional and marketing, per-language variants, sender configuration)
• Notification rules (triggers, channels, cooldowns, suppression lists)
• Marketing attribution (UTMs, referral codes, affiliate links, landing pages)
• Support tickets (if the ticketing tool is being replaced)
• Custom fields and tags (every CRM has them; every CRM labels them differently)

Common blockers and how we resolve them

These are the six blockers we encounter most often. Naming them up front is the cheapest way to remove them.

1. Legacy data encoding issues. Older CRM databases frequently store client names in mixed encodings (Latin-1, Windows-1252, UTF-8) without a consistent marker. Names with accented characters round-trip incorrectly. We resolve this by detecting encoding per row using a heuristic pass, normalizing everything to UTF-8 in the staging layer, and surfacing ambiguous cases for ops review before load.

2. PSP re-certification gaps. Some PSPs require re-certification when the merchant platform changes, even if the merchant ID stays the same. We resolve this by contacting each PSP during Phase 1, obtaining their re-certification checklist, and running the test transactions in Phase 3 against the checklist. If a PSP quotes longer than 5 business days, we flag it in the risk register and plan a staged cutover where that PSP is enabled after go-live.

3. MT5 group configuration drift. Over years of operation, MT5 groups accumulate manual edits: custom commission rules per group, symbol exceptions, margin overrides. The documented config and the live config rarely match. We resolve this by extracting live group configs directly from the MT5 server via the manager API in Phase 1, diffing against what the client believes the config to be, and producing a reconciled target config for Phase 4.

4. IB commission-rule edge cases. Every IB program has special cases: grandfather clauses for long-tenured IBs, one-off override rates, suspended IBs with accrued-but-unpaid balances, IBs whose payout method changed mid-quarter. We resolve this by extracting the full commission ledger, not just the current rule set, and replaying it in staging to confirm our IB engine produces the same per-IB balance as the source system to the cent.

5. Missing historical audit logs. Regulators in most jurisdictions require a continuous audit trail. If the source CRM's audit log is incomplete or has been truncated, the migration cannot invent history. We resolve this by preserving the source audit log as a read-only archive inside the new tenant, accessible via a dedicated compliance view, while the new audit log starts fresh on cutover day.

6. Regulatory sign-off windows. Some regulators require advance notice of a material technology change. Windows vary from 0 days to 30 days. We resolve this by asking the compliance lead in Phase 1 to confirm notice requirements, and by timing the public announcement and sign-off submission so that the regulator-mandated window closes before the Phase 4 cutover date.

What "zero downtime" actually means

Zero downtime in this guide means: at no point is a client unable to access their account, check their balance, or trade on MT5. It does not mean that every administrative function is available at every moment. During the Phase 4 cutover window (typically a 2–4 hour low-volume window, often a Sunday), the following may be briefly unavailable:

• The client portal login page (5–15 minutes while DNS and session stores switch over)
• Deposit initiation from the client portal (10–30 minutes while PSP webhooks are re-pointed)
• Admin panel for ops staff (up to 1 hour while permissions and SSO are validated)

Trading on MT5 is never interrupted. Open positions are never touched. Pending orders remain pending. Client balances are frozen read-only during the switch and unfrozen once reconciliation is confirmed. If any of these windows needs to be zero rather than short, we discuss it in Phase 1 and plan a more elaborate blue-green cutover.

Timeline template

The following is the standard 11-day template. It compresses to 7 days for smaller brokers and extends to 14 days when PSP re-certifications or regulatory windows demand it.

For a 7-day compressed plan we collapse Phases 2 and 3 into overlapping 3-day blocks. For a 14-day extended plan we allow 2 additional days in Phase 2 for reconciliation and 1 additional day each in Phases 3 and 4 for regulatory sign-off.
